Convert word files to PDF format results in grey vertical bars in PDF file after conversion

We are using registered version of Aspose.Words.dll(9.0 .0) for converting word file to pdf

After the files were converted, they all ended up with an additional vertical grey bar on the left side of the page.
POSSept11_SFLA.doc is attached. It is the original Word file before application converted it to PDF.
1.7.1 POSSept11_SFLA.pdf is attached. It is the same file after application converted it to PDF. Note the vertical grey bar in the third column from the left.
If you simply print the Word file to Adobe PDF printer, no grey bars result.
Following is the code we are using:

switch (sourceFileExt)
{
    case ".doc":
    case ".docx":
        Aspose.Words.Document doc = new Aspose.Words.Document(sourceFilePath);
        doc.SaveToPdf(destinationFilePath);
}

This is very urgent issue. Can you please provide the fix for this asap?

Thanks,

Hi Viral,
Thanks for your request. I cannot reproduce the problem on my side. I used the latest version of Aspose.Words for testing. You can download the latest version from here:
